Serial no. 275,619. 7 My invention relates to door holding do 38 are connected by a coiled spring 40; In vices and an object is to provide a device installing the device, the plate 10 by means which will not only prevent doors such as of fastening'devices extending through the garage doors from being blown shut when 1 holes 12 secured to the underside of a hori- 60 they are open but whiohwill also tend to zontal member H of the building, this horiprevent them from swinging open when they zontal. member being located adjacent the are closed. I accomplish the objects of my 1 upper edge or the door 1). The plate as invention by providing adevice embodying shown in Fig. 1, is secured to the member I a spring which is'placed under tension when near the hinged margin of the door) The 65 10 the door is swung either from open position bracket 32 is secured to the door D in such toward closed position or from closed posiposition that the parts of the device when tion toward open position, the spring being the door is closed have the position shown so connected that it passesovcr dead center by full lines in Fig. 1 and with the spring when the door is in partly open position. 10 not under tension .or under only slight 70 V 1 The full objects and advantages out my intension. The stop 18 is adjusted to such povention will appear in connection with the sition that the bar 26 will contact therewith detailed description thereof, andv the novel J when the door is swung open to the position features of my inventive idea willlbeparticwhich it is desired it to have when opened I ularly pointed out in the claims. f to its full extent.

Then the As shown in the drawings, 1 provide'an' spring has passed dead center, the tension '90 attaching plate 10 having a number of holes thereof tends to swing the door into open po- 12therein for securing it in place. Near one sition as shown in Fig. 2 and the spring acts edge of this plate, there is an offset portion to prevent the door from being blown shut. 1.4; containing an elongated slot 16. A slid As shown in Fig. 5, the adjustable stop may able stop 18 is held in adjusted position be made in the form of abufler for use in 5 40 along the slot by a bolt 20 passing through connection with heavy doors. The bolt 20 the slot and the stop. Near the opposite edge in this construction adjustably holds a plate of the plate and vnear one corner thereof, 10 having flanges 4 1 and 46 on its two oppothere is a boss 22 which is raised to such an site ends. A rod 41-8 passes slidably through extent as to bring it on a level withthe otithe flange 14iwhile this rod has a head 50 set portion 14. The boss 22 is provided with extending slidably through the flange 4:6 and a central hole through which passes a rivet normally projected beyond the flange 46 by 2 L, this rivet also passing through a hole in a coiled spring 52 surrounding the rod 1-8 one end of a bar 26 whereby this bar is pivand interposed between the flange 14 and the oted to the plate. The other end of the bar head 50. \Nhen the door is swung into open 5o 26 is pivotally attached to one end of a bar position, the bar 26 engages the head 50 so 28 by means of a rivet 30. The other end of that the shock is cushioned due to the fact the bar 28 is pivotally attached to a securing that the head 50 is resiliently backed up by bracket 32 by. a rivet 3 The bar 26 between the spring 52. its ends is provided with a projection 36 while I claim: 1 v the plate 10 at one of its corners is provided 1. A door holding device comprising a with a projection 38. The projections 36 and plate adapted to be secured to a fixed part of an article provided With a door, said plate having an offset portion provided With a longitudinal slot, a stop member adjustably secured along said slot, a bar pivoted to said plate, a second bar pivoted to said first bar, an attaching member pivoted to the outer end of said second bar for attachment to the door, and a spring attached to said first bar in such manner that the spring passes over dead center when said first bar is substantially parallel to the length of said plate, said first bar engaging said stop member when the door is fully open.

2. A door holding device comprising a plate adapted to be secured to a fixed part of an article provided with a door, said plate having an offset portion provided with a longitudinal slot, a stop member adjustably secured along said slot, a boss carried by said plate and which is raised to such an extent as to bring it on a level with said offset portion, a bar pivoted to said boss, a second bar pivoted to said first bar, an attaching member pivoted to the outer end of said second bar for attachment to the door, and a spring attached to said first bar in such manner that the spring passes over dcadcenter when said first bar is substantially parallel to the length of said plate, said first bar engaging said stop mem her when the door is fully opened.

3. A door holding device comprising a plate adapted to be secured to a fixed part of an article provided With a door, a bar pivoted to said plate, a second bar pivoted to the outer end of said first bar, an attaching member pivoted tothe outer end of said second bar for attachment to the door, a projection extend ing out -from said plate, a second projection extending out from an intermediate point of said first bar, and a coiled spring connecting said projections in such manner that the spring passes over dead center when said first bar is substantially parallel to the length of said plate.

4. A door holding device comprising a plate adapted to be secured to a fixed part of an article provided with a door, said plate having an offset portion at one of its edges provided with a longitudinal slot, a stop member adjustably secured along said slot, a bar pivoted to said plate at one of its corners opposite said edge, a second bar pivoted to said first bar, an attaching member pivoted to the outer end of said second bar for attachment to the door, and a coiled spring attached at one end to the other corner of said plate opposite said ed e and attached at its other end to an intermediate point of said first bar.

5. A door holding device plate adapted to be secured to a fixed part of an article provided with a door, said plate having an offset portion provided with a longitudinal slot, a plate adjustably secured along said slot, said plate having flanges at both of its ends, a rod extending slidably through one of said flanges, a head for said rod extending slidably through the other of said flanges, a coiled spring normaily holding said head projected beyond the flange through which it passes, a bar pivoted to said plate, a second bar pivoted to said first bar, an attaching member pivoted to theouter end of said second bar -for attachment to the door, and a spring attached to said first bar in such manner that said spring passes over dead center when said first bar issubstantially parallel to thclength of said plate, said first bar engaging said head when the door is fully open.

In testimony whereof I hereunto afiix my signature.
